What are the scientific journals dedicated to artificial general intelligence?
There's also the journal Advances in Cognitive Systems. According to their website

Advances in Cognitive Systems (ISSN 2324-8416) publishes research articles, review papers, and essays on the computational study of human-level intelligence, integrated intelligent systems, cognitive architectures, and related topics. Research on cognitive systems is distinguished by a focus on high-level cognition, reliance on rich, structured representations, a systems-level perspective, use of heuristics to handle complexity, and incorporation of insights about human thinking. Advances in Cognitive Systems reviews submissions within approximately three months and publishes accepted papers on the journal Web site immediately upon receipt of final versions. Articles are distributed freely over the internet by the Cognitive Systems Foundation.
